Definitions

  • This invention relates, generally, to devices that enable people having low vision to read printed documents. More particularly, it relates to a camera in an electronic magnifier requiring symmetrical illumination when used in contact with or near a target object such as a printed document.
  • the glass must be positioned a specific distance from the paper to obtain optimal magnification, and the paper must be well-illuminated.
  • Such systems typically include a magnifier system where magnification is determined by the distance to the object to be viewed, the ratio of sensor to display size, and optical features of the camera. In the future, the optical features of the camera may perform the magnification.
  • the long-standing but heretofore unfulfilled need for a low vision reader including an LCD display of a well-illuminated object is now met by a new, useful, and non-obvious invention.
  • the invention also fulfills the need for a device that need not be held over a document in hovering relation thereto when in use.
  • a hollow structure includes a top housing and a bottom housing that are connected to one another.
  • a camera aperture is formed in the bottom housing and a transparent optical light guide lens is disposed in closing relation to the camera aperture so that all light entering the camera aperture must first pass through the optical light guide lens.
  • the device rests atop the document or other object being viewed. Accordingly, no stands or other means for hovering the reader over the document are required.
  • the reader is easily slideable from one part of the document to the next, and the part of the document being viewed is always well-illuminated with symmetrical lighting so that there are no dark spots or other abnormalities in the LCD output display.
  • a first undercut is formed in the bottom housing adjacent a first edge of the camera aperture and a second undercut is formed in the bottom housing adjacent a second end of the camera aperture.
  • the optical light guide lens has a first mounting flange at a first end thereof, a second mounting flange at a second end thereof, and a raised section between the first and second mounting flanges.
  • the first undercut is defined by a first overhang and is adapted to receive the first mounting flange.
  • the second undercut is defined by a second overhang and is adapted to receive the second mounting flange.
  • the first mounting flange has a length in excess of a depth of the first undercut so that a first space is created between the raised section of the light guide lens and the first overhang.
  • the second mounting flange also has a length in excess of a depth of the second undercut so that a second space is created between the raised section of the light guide lens and the second overhang.
  • a printed circuit board is disposed in overlying relation to an interior side of the optical light guide lens.
  • a window or opening is formed in the printed circuit board so that light can pass through the light guide lens.
  • a first pair of light-emitting diodes is secured to a first end of the printed circuit board adjacent a first end of the camera aperture and a second pair of light-emitting diodes is secured to a second end of the printed circuit board adjacent a second end of the camera aperture.
  • the first pair of light-emitting diodes is disposed in the first space on opposite sides of a longitudinal axis of symmetry of the camera aperture and the second pair of light-emitting diodes is disposed in the second space on opposite sides of the longitudinal axis of symmetry of the camera aperture.
  • An important advantage of the invention is that the object being viewed is illuminated in an optimal way by the light emitting diodes (LEDs) that are strategically positioned about the perimeter of the optical light guide lens.
  • the optical light guide lens has a specific structure that bends light rays emitted by the LEDs into the object being scanned without any reflections of the LEDs on the camera.
  • Another major advantage is that the novel structure minimizes light leakage about the periphery of the optical light guide lens.
  • FIG. 1 is an exploded perspective view of a bottom housing
  • FIG. 2 is a perspective view of the interior side of the novel light guide lens
  • FIG. 3 is a perspective view of the exterior side of the novel light guide lens
  • FIG. 4 is a cross-sectional view taken along line 4 - 4 in FIG. 1 and along line 4 - 4 in FIG. 2 ;
  • FIG. 5 is a cross-sectional view depicting the light guide lens and the bottom housing when connected to one another, including an LED, the PCB, and the stiffener;
  • FIG. 6A is a simple ray trace diagram indicating how light rays are affected by the mirror of the incorporated disclosure
  • FIG. 6B is a raytrace diagram indicating the effectiveness of the angle ⁇ .
  • FIG. 6C is a raytrace diagram indicating how the novel positioning of LEDs relative to the novel structure of the optical light guide lens accomplishes the even illumination of the object being viewed.
  • FIG. 1 of the present disclosure depicts bottom housing 12 that is engaged at its periphery by sidewalls 14 a , 14 b , 14 c , and 14 d of top housing 10 depicted in FIGS. 2 , 3 and 4 of the incorporated disclosure.
  • rectangular opening 12 a is formed in said bottom housing 12 at a first end thereof so that when bottom housing 12 is attached to top housing 10 of the incorporated structure, opening 12 a is in registration with mirror 26 of the structure depicted in the incorporated disclosure.
  • rectangular opening 12 a is understood to be a camera aperture.
  • the user of the device slides opening 12 a over the text or other image to be enlarged and the enlarged text or image appears on LCD screen 14 , depicted in FIG. 2 of the incorporated disclosure.
  • Light guide lens 14 of this disclosure is positioned in registration with camera aperture 12 a when the novel device is fully assembled.
  • Light guide lens 14 is made of a clear plastic, preferably Plexiglas® acrylic resin.
  • Upstanding pegs 16 , 17 , and 18 are formed integrally with light guide lens 14 and are adapted to engage openings denoted 16 a , 17 a , and 18 a , respectively, formed in bottom housing 12 about the periphery of aperture 12 a . More particularly, prior to attaching bottom housing 12 to top housing 10 of the incorporated disclosure, printed circuit board (PCB) 15 , as depicted in FIG. 1 , is placed in closing relation to camera aperture 12 a on the interior side thereof.
  • PCB printed circuit board
  • Opaque stiffener 19 is then placed in overlying relation to said PCB, and novel light guide lens 14 is positioned in underlying relation to said PCB by inserting pegs 16 , 17 , and 18 into peg bores 16 a , 17 a , and 18 a , respectively.
  • the interior side of light guide lens 14 is depicted in FIG. 1 and said PCB overlies said interior side.
  • Opening or window 15 a is formed in the center of PCB 15 and opening or window 19 a is formed in the center of stiffener 19 so that light rays can enter light guide lens 14 .
  • Exterior surface 15 b of PCB 15 is preferably black in color to provide a mask around camera aperture 12 a and to reduce stray light effects that may propagate towards the camera.
  • Light guide lens 14 includes a flange 20 at its opposite ends. Center part 22 of light guide lens 14 is raised with respect to said flanges, thereby creating cavity 24 ( FIG. 3-5 ). Angle ⁇ is one hundred thirty five degrees (135°).
  • peg 16 is positioned within arcuate recess 26 formed in a transverse edge 28 a of raised part 22 .
  • Edge 28 a is bounded by longitudinally-extending edges 28 b , 28 b .
  • Second transverse edge 30 a on the opposite side of raised section 22 , is bounded by longitudinal edges 30 b , 30 b .
  • FIG. 2 also indicates the positions of four (4) light emitting diodes (LEDs), collectively denoted 34 .
  • LEDs light emitting diodes
  • a first pair of said LEDs are positioned at a first end of light guide lens 14 on opposite sides of longitudinal axis of symmetry 14 a of said light guide lens in symmetrical relation to one another, and a second pair of said LEDs are positioned at a second end of light guide lens 14 on opposite sides of said longitudinal axis of symmetry in symmetrical relation to one another.
  • PCB 15 is not depicted in FIG. 2 , it should be understood that LEDs 34 are secured to said PCB.
  • the height difference between mounting flanges 20 , 20 and raised section 22 is sufficient to accommodate said LEDs.
  • FIG. 3 depicts the exterior side of light guide lens 14 .
  • Each wall 24 a is angled relative to the plane of raised section 22 at an angle ⁇ that is equal to one hundred thirty five degrees (135°) as aforesaid.
  • FIG. 4 provides a cross-sectional view of optical light guide lens 14 . All of the parts indicated by reference numerals in said FIG. 4 have been identified above.
  • FIG. 5 depicts bottom housing 12 having undercut 32 formed therein, defined by overhang 33 .
  • Each flange 20 of light guide lens 14 has an extent that exceeds the depth of its associated undercut 32 so that space 36 is created between raised center part 22 and overhang 33 .
  • FIG. 6A depicts a simple raytrace modeling the scattered light from the land in front of the LEDs. This shows the path of the light up onto the mirror, where it is projected downwardly into the field of view.
  • the scattered light from this area is kept inside the window to contribute to the general illumination.
  • FIG. 6C depicts a simple model of the LED position. It shows that only a small pencil of light will strike the mirror at a low angle, outside of the field of view of the camera and any reflected light will be directed onto the back of PCB 15 .
  • each LED 34 is positioned in a space created by the step between raised section 22 and mounting flange 20 of optical light guide lens 14 , said space being further created by the structuring of each mounting flange to exceed the depth of its associated undercut 32 as explained above. As best understood in connection with FIG. 5 , this positions each LED 34 at a substantially forty five degree (45°) angle relative to its associated sidewall 24 a . Each LED is thus positioned outside of cavity 24 and the light from each LED must pass through optical light guide lens 14 to illuminate the object being sensed by the camera of the incorporated disclosure. This novel structure eliminates the poor illumination characteristics of prior art devices.
  • the slideability of the novel structure over the document or other object being viewed is another important feature of the invention.
  • the contact between the device and the object eliminates the need for stands or manual holding of the device in hovering relation to the object.
  • the flat, low friction bottom of the device is understood from all of the figures but is perhaps best understood in connection with FIGS. 4 and 5 .
